【摘要】 2019年10月12日广西北流—广东化州发生M_S5.2级地震,广东省地震台网中心值班员在速报过程中,发现为同源双震事件且后面的地震震级较大,其后最大的余震也是双震。两次都为典型的同源双震类型,震中位置处于广东、广西交界。基于此次地震的特殊性,对同源双震速报情况进行了回顾总结,分析了其地震特征和定位精度,并给出同源双震处理的相关建议。更多还原

【Abstract】 On October 12 th,2019,an M_S5.2 earthquake occurred in the junction of Guangdong Huazhou and Guangxi Beiliu. During the rapid report,the staff on duty at the center of the Guangdong Seismic Network found that the earthquakes were homologous double events with larger subsequent earthquake,and the largest aftershocks were also homologous double events. Both are typical types of homologous double events,and the epicenter of those earthquakes lie in the junction of Guangxi and Guangdong. Own to the particularity of the four earthquakes,the paper reviewed and summarized the earthquake quick report of two homologous double events,and analyzed the seismic characteristics and earthquake location accuracy. At last,the paper gave some suggestions on the process of homologous double events.更多还原
